The Facedown Mirror is a
optical device that has 2 mirrors mounted on it. The vertical mirror
reflects the image you are looking at, and the horizontal mirror reverses
it so it has the correct orientation. When you look down on the
mirror, the image looks as if you are looking forward.

This device is primarily used for watching TV or
seeing things and people without looking up. Compliance to the
facedown position is enhanced with this mirror.
